Peach tree, ‘Burpeachforty’

ABSTRACT

A new and distinct variety of peach tree ( Prunus persica ), which is denominated varietally as ‘Burpeachforty’, and which further produces an attractively colored yellow fleshed, clingstone peach which is mature for harvesting and shipment approximately June 12 to June 19 under the ecological conditions prevailing in the San Joaquin Valley of central California.

Latin name: Prunus persica.

Varietal denomination: Burpeachforty.

BACKGROUND OF THE NEW VARIETY

The present variety of peach tree resulted from an on-going program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties, and rootstocks, by creating and releasing promising selections of Prunus, Malus, Punica and Juglans species. To this end we make both controlled and hybrid cross-pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected.

The seedling, ‘Burpeachforty’ was originated by us, and selected from a population of seedlings growing in our experimental orchards which are located near Fowler, Calif. The seedlings, grown on their own roots, were derived from planting seed of a controlled cross-pollination of an un-named, non-patented, proprietary seedling which produces a yellow-fleshed, clingstone peach which was used as the female parent. The male or pollen parent, on the other hand, produced a sub-acidic, white-fleshed peach and is further varietally identified as ‘Burpeachthirtyfive’ (U.S. Plant Pat. No. 25,744). The resulting fruit from this cross-pollination was collected from the female parent at a mature stage, and seeds were extracted from this same fruit in June of 2007. After a period of stratification, the seeds were placed in our greenhouse by population, and then field planted for tree establishment, and ultimately to exhibit fruit for further evaluation. One yellow fleshed peach seedling, which is the present variety, exhibited especially desirable characteristics, and was then designated as ‘Q13.052’. This seedling was marked for subsequent observation. After the 2010 fruiting season, the new variety of peach tree was selected for advanced evaluation and repropagation.

ASEXUAL REPRODUCTION

Asexual reproduction of this new and distinct variety of peach tree was accomplished by budding the new peach tree onto 30 trees which were established with ‘Nemaguard’ Rootstock (un-patented). This asexual reproduction was performed by us in our experimental orchard which is located near Fowler, Calif. Subsequent evaluations of these asexually reproduced trees have demonstrated to us that those asexual reproduced trees display all the characteristics as seen in the original plant. All characteristics of the original tree, and its fruit, were established, and appear to be transmitted through these succeeding asexual propagations.

SUMMARY OF VARIETY

‘Burpeachforty’ is a new and distinct variety of peach tree, which is considered of relatively large size, and which has a vigorous growth habit. This new tree is also a regular and productive bearer of relatively large, firm, yellow-fleshed, acidic clingstone fruit which have a very good flavor, and eating qualities. This new peach tree has a medium chilling requirement of approximately 500 hours, and further produces relatively uniformly sized fruit throughout the tree's canopy. In addition to the foregoing, the fruit of the new peach tree also appears to have good handling and shipping qualities. The ‘Burpeachforty’ peach tree bears fruit which are typically ripe for commercial harvesting, and shipment, on approximately June 12 to June 19 under the usual ecological conditions prevailing in the San Joaquin Valley of central California. In relative comparison to the ‘June Flame’ peach tree ‘Burpeachsix’ (U.S. Pat. No. 13,392), which is the closest known variety, the new variety of peach tree bears fruit that is clingstone by nature, whereas the ‘June Flame’ peach tree produces fruit which exhibits a freestone character. Further, the fruit produced by the new variety exhibits a more oblate, and less elongated shape than the fruit produced by the ‘June Flame’ peach tree when the fruit of this patented tree is used as the commercial comparative variety. In relative comparison to the unnamed, and unpatented seed parent tree, the new variety produces fruit which is considered as having non-melting flesh, whereas the seed parent produces fruit having a melting flesh character. The new variety differs from the pollen parent, in that, the current new variety produces fruit which is both yellow-fleshed, and further exhibits a classic acidic flavor, while, on the other hand, the pollen parent produces fruit which is sub-acidic. In addition to the foregoing, the new peach tree variety produces fruit which has a yellow-flesh, as compared to the pollen parent which produces fruit having a white-flesh.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following has been observed during the tenth fruiting season, and under the ecological conditions prevailing at the orchards of the assignee and which are located near the town of Fowler, county of Fresno, state of California. All major color code designations are by reference to The R.H.S. Color Chart (Royal Horticultural Society, Fourth Edition, 2001) and which are provided by The Royal Horticultural Society of Great Britain. Common color names are also occasionally used.

TREE

-   Size:     -   -   Generally.—Considered medium to medium-large in its growth             pattern as compared to other common commercial peach             cultivars ripening in the same season of maturity. The tree             of the present variety was pruned to a height of             approximately 270.0 cm. to about 310.0 cm. at commercial             maturity. -   Width: Approximately 265.0 cm. -   Vigor: Considered moderately vigorous. The present peach tree     variety grew from about 175.0 cm. to about 180.0 cm, in height,     during the first growing season. The new variety of peach tree was     pruned to a height of approximately 150.0 cm. during the first     dormant season, and primary scaffolds were then selected for the     desired tree structure. -   Productivity: Productive. Fruit set varies from more than the     desired crop load, to levels higher than the desired amounts, when     the new variety is grown in a suitable horticultural zone, and under     appropriate commercial nursery conditions. The fruit set is spaced,     by thinning, to develop the remaining fruit into the desired     market-sized fruit. The number of the fruit set varies with the     prevailing climatic conditions, and the cultural practices employed. -   Fruit bearing: Regular. Fruit set for the new variety has been more     than adequate during the previous years of observation, and thinning     of the canopy was necessary during the past 6 years on both the     original seedling, and on subsequent asexually reproduced trees. -   Tree form: Upright, and pruned into a vase shape. -   Canopy density: Considered moderately dense. It has been discovered     that pruning the branches from the center of the tree to obtain a     resulting vase-shape allows for enhanced air movement, and     appropriate amounts of sunlight to improve fruit color, and renewal     of fruiting wood throughout the tree. -   Hardiness: The present tree was grown and evaluated in USDA     Hardiness Zone 9. The calculated winter chilling requirements of the     new tree is approximately 500 hours at a temperature below 7.0     degrees C. The present variety appears to be hardy under typical     central San Joaquin Valley climatic conditions.

TRUNK

-   Diameter: Approximately 17.5 cm in diameter when measured at a     distance of approximately 15.24 cm. above the soil level. This     measurement was taken at the end of the 7th growing season. -   Bark texture: Considered moderately rough, with folds of papery     scarfskin being present. Since bark development, and coloration     change with advancing tree age, this characteristic varies with the     tree vigor, age, and regional environmental conditions. Therefore,     this growing trait is not a dependable descriptor of the new     variety. -   Lenticels: Numerous flat, oval lenticels are present. The lenticels     range in size from approximately 8.0 millimeters to about 10.0 mm.     in width; and between about 1.0 and about 2.0 millimeters in height.     The development and size of the trunk lenticels can be influenced,     to some degree, by the ambient growing conditions, and are not,     necessarily, a dependable characteristic of this variety. As trees     of this variety mature, lenticels are present, but they are     generally covered by increasing layers of cork (mature bark), and     therefore become less apparent to an observer. -   Lenticel color: Considered an orange-brown, (RHS Greyed-Orange Group     164 A). -   Bark coloration: Variable, but it is generally considered to be a     grey-brown, (Grey-Brown Group RHS N199 B). This bark description was     taken from trees in their sixth leaf, and which have ruptured the     scarf skin, and which further also have developed bark furrowing     that is much more typical of the bark of older trees. It should be     noted that the coloration of the bark is influenced, and varies, as     the smoother, darker background color approaches other bark features     such as the lenticels, and the initial fissures which form a feature     of the scarf skin development.

BRANCHES

-   Size: Considered medium-large for the species. -   Diameter: Average as compared to other peach tree varieties. The     branches have a diameter of about 11.0 centimeters when measured     during the 6th year after grafting. -   Flowering shoot thickness: Approximately 8.5 mm. -   Surface texture: Average, and appearing relatively smooth, but with     more furrowing on wood which is several years old. -   Crotch angles: Primary branches are considered variable, and are     usually growing at an angle of about 42 to about 50 degrees when     measured from a horizontal plane. This particular characteristic can     vary due to influences such as variable ecological conditions, and     the current cultural practices employed. -   Current season shoots:     -   -   Surface texture.—Substantially glabrous. -   Internode length: Approximately 2.4 cm. -   Color of mature branches: Approximately Grey brown, (Greyed-Orange     Group RHS 177 C). -   Current season's shoots:     -   -   Color.—Light green, (Yellow-Green Group RHS 145 C). The             color of new shoot tips is considered a bright and shiny             green (Yellow-Green Group RHS 146 D). The vegetative shoot             color can be significantly influenced by plant nutrition,             irrigation practices, and exposure to sunlight, and             therefore should not be considered a consistent botanical             characteristic of this new variety of peach tree.

LEAVES

-   Size: Considered somewhat elongated, and narrow for the species.     Leaf measurements have been taken from vigorous, upright,     current-season growth, taken at approximately mid-shoot. It should     be understood that the leaf size is often influenced by the     prevailing growing conditions, quality of sunlight, and the growth     location of the leaf within the tree canopy. For this reason, leaf     sizes can vary, sometimes significantly, based upon the ambient, and     other cultural factors listed above, and are not typically     considered a dependable botanical descriptor. -   Leaf length: Approximately 158.0 to about 168.0 millimeters. -   Leaf width: Approximately 28.0 to about 32.0 millimeters. -   Leaf base-shape: The leaves generally exhibit equal marginal     symmetry relative to the longitudinal axis of the leaf. -   Leaf form: Lanceolate. -   Leaf tip form: Acuminate. -   Leaf color:     -   -   Upper and lower leaf surfaces.—Medium green, (approximately             Green Group RHS 137 B). -   Leaf texture:     -   -   Upper leaf surface.—Glabrous.         -   Lower leaf surface.—Glabrous. -   Leaf color:     -   -   Lower leaf surface.—Medium green, (approximately Green Group             RHS 137 D). -   Leaf venation: Pinnately veined. -   Mid-vein:     -   -   Color.—Considered a light yellow, (approximately             Greyed-Yellow Group RHS 160 C) when viewed in the early to             mid-period of the growing season. -   Leaf marginal form: Gently undulating.     -   -   Marginal edge shape.—Considered finely crenate.         -   Uniformity.—Considered generally uniform. -   Leaf petioles:     -   -   Form.—Considered canaliculated, and having a more pronounced             trough when viewed from the dorsal aspect. The petiole             margin is considered rounded when viewed from the ventral             aspect.         -   Size.—Considered medium-small for the species.         -   Length.—About 8.0 to about 11.0 mm.         -   Diameter.—About 1.5 to about 2.0 mm.         -   Color.—Light yellow green, (approximately RHS Yellow-Green             Group 145 A).         -   Surface texture.—Substantially glabrous.         -   Strength.—The pedicle is considered durable for the species             until senescence. -   Leaf glands:     -   -   Size.—Considered relatively small for the species;             approximately 2.0 mm. in length; and about 1.0 mm. in             height.         -   Number.—Generally one and less common two glands appear per             marginal side. Observations of more than two glands per             marginal side are very uncommon.         -   Type.—Leaf glands located at the base of the leaf are             predominantly reniform in shape. An additional one to two,             or occasionally more leaf glands, which appear globose, and             stalked, are often present at the basal margin of the leaf             petiole as well.         -   Color.—Considered a medium-dark brown, approximately (RHS             Brown Group 199 A). Typically the coloration of the glands             darken, and occasionally begins to desiccate during the             mid-late portion of the growing season. -   Leaf stipules:     -   -   Size.—Medium large for this variety.         -   Number.—Typically 2 per leaf bud, and up to 6 per shoot tip.         -   Form.—Lanceolate, and having a serrated marginal edge.         -   Color.—Green, (approximately RHS Green Group 137 B) when             young, but graduating to a brown color, (approximately RHS             Greyed-Orange Group 165 A) with advancing senescence. The             leaf stipules are generally considered to be early             deciduous.

FLOWER BUDS

-   Hardiness: No winter injury (bud death) has been noted during the     last several years of observation in the central San Joaquin Valley.     The new variety of peach tree has not been intentionally subjected     to drought, cold or heat stress, and therefore this information is     not available. -   Flower bud:     -   -   Size.—Variable, and dependent upon the state of maturity.             The flower buds, as described, were observed approximately 7             days prior to bloom.         -   Length.—Approximately 15.5 millimeters.         -   Diameter.—Approximately 8.5 millimeters.         -   Surface texture.—Pubescent.         -   Orientation.—Considered appressed, but appearing less so as             the blossoms near opening. -   Bud scale color: Grey-orange, (approximately Greyed-Orange Group RHS     175 A).

FRUIT

-   Maturity when described: Firm ripe condition (shipping ripe). -   Date of first picking: Approximately Jun. 12, 2016. -   Date of last picking: Jun. 19, 2016. The date of harvest can vary     with the prevailing climatic conditions, crop loads and the current     climatic and cultural practices which are utilized. -   Size:     -   -   Generally.—Considered medium-large for the species. -   Average cheek diameter: Approximately 74.0 to about 79.0     millimeters. -   Average axial diameter: Approximately 72.0 to about 77.0     millimeters. -   Typical fruit weight: Approximately 215.0 grams. The aforementioned     characteristics are quite dependent upon the prevailing cultural     practices, and growing conditions, and therefore is not a     particularly distinctive characteristic of the new variety. -   Fruit form:     -   -   Generally.—Considered globose. The fruit is generally very             uniform in symmetry. -   Mucron tip: Absent. -   Fruit suture:     -   -   Generally.—No stitching exists along the suture line. -   Suture:     -   -   Color.—Generally, the fruit appears blushed to the same             degree as the skin, (approximately RHS Orange-Red Group 34             A). -   Ventral surface:     -   -   Form.—Considered even, and uniform in appearance, when it is             viewed from the lateral, sutural plane. -   Apex:     -   -   Shape.—Rounded to slightly rutuse. -   Base:     -   -   Shape.—Generally smooth. -   Stem cavity:     -   -   Generally.—The stem cavity extends in a rounded circular             form which is generally considered uniform. The stem cavity             is rounded but slightly extended toward the suture. The             average depth of the stem cavity is about 8.0-10.0 mm. The             average width of the stem cavity is about 26.0 mm. The             average length of the stem cavity, when measured in the             suturial plane is about 45.0 mm. -   Fruit skin:     -   -   Thickness.—Considered medium in thickness, and tenacious to             the flesh.         -   Surface texture.—A short and fine pubescence is present. The             pubescence is moderately abundant.         -   Taste.—Non-astringent.         -   Tendency to crack.—Not observed in the previous years of             observation, and evaluation. -   Fruit skin color:     -   -   Blush color.—Generally speaking, a red blush exists on a             majority of the skin surface of the fruit (approximately RHS             Orange-Red Group 34 A). The blush is more typically present             on the portions of the fruit facing the sunlight. Further,             the blush of the fruit typically covers approximately             65%-85% of the fruit skin surface. The percentage of the             blush on the fruit skin surface can vary, and is generally             dependent upon the fruit's exposure to direct sunlight;             specific fruit maturity; and also the prevailing ecological             and cultural conditions under which the fruit was grown. -   Ground color: A medium light orange-yellow, (approximately RHS     Yellow-Orange Group 23 C). The ground color of the fruit can vary     significantly based upon the maturity of the fruit when this     measurement is taken, and generally gains or develops a lighter, and     green cast with advancing maturity. -   Fruit glossiness: The fruit is not considered to be glossy. -   Fruit stem:     -   -   Size.—Medium in length, approximately 6.0 to about 8.0             millimeters.         -   Diameter.—Approximately 2.0 to about 3.0 millimeters.         -   Color.—Pale yellow-green, (approximately RHS Yellow-Green             Group N144 C). -   Fruit flesh:     -   -   Ripening.—Considered even.         -   Texture.—Firm, crunchy, juicy and dense. Considered             firm-melting in flesh texture.         -   Fibers.—Present, but not prominent.         -   Aroma.—Slight.         -   Eating quality.—Considered very good.         -   Flavor.—Considered balanced with sweetness and acidity.         -   Juice production.—Moderate.         -   Brix.—About 11.0 to 13.5 degrees. This characteristic varies             slightly with the number of fruit per tree; the maturity of             fruit when harvested; the prevailing cultural practices; and             the ambient climatic conditions under which the fruit was             grown.         -   Acidity.—Considered low. Approximately 0.8 titratable             acidity. Acid levels assayed from fruit flesh can vary based             upon the fruit maturity, sunlight exposure, and climatic,             regional and cultural influences or practices employed.         -   Flesh color.—It is considered yellow in color,             (approximately RHS Yellow-Orange Group 17 D). A slight             pigmentation of a pink-red color can be seen radiating from             the stone (approximately RHS Red Group 39 A).

STONE

-   Type: Considered a clingstone. -   Size: It is generally considered to be medium to small for the     species. The stone size varies significantly depending upon the tree     vigor, the crop load, and the prevailing growing and cultural     conditions under which the tree was grown. -   Stone length: Average, about 29.0 to about 32.0 millimeters. -   Stone width: Average, about 21.0 to about 24.0 millimeters. -   Stone diameter: Average, about 17.0 to about 20.0 millimeters. -   Stone form: Roughly ovoid. -   Stone base:     -   -   Shape.—The stone is considered shortly attenuate. -   Stone apex:     -   -   Shape.—The stone exhibits a slightly acute apex. -   Stone surface:     -   -   Surface texture.—Considered irregularly furrowed toward the             apex. Further, more pitting exists in the mid-portion of the             stone (laterally), and is more common toward the base.         -   Ridges.—Ridging is generally more prominent, and is usually             oriented substantially parallel, and laterally relative to             the ventral and dorsal margins.         -   Ventral edge.—The ventral edge is generally described as             having adjoining ridges formed from each hemisphere. There             are longitudinal grooves running alongside this joined             ventral suture.         -   Dorsal edge.—Shape — Generally considered even. The folds of             the surface ridges appearing on the external margins often             end gently along the suture. -   Stone color: The color of a mature, dry stone is generally     considered a dull brown, approximately (RHS Greyed-Orange Group 165     D). The observed stone color can vary based upon how recently the     fruit has ripened, the degree of oxidation which has taken place,     and any blanching which has occurred due to the exposure sunlight. -   Tendency to split: Splitting has only rarely been noted. -   Kernel:     -   -   Length.—Approximately 14.0-17.0 millimeters.         -   Width.—Approximately 12.0-15.0 millimeters.         -   Thickness.—4.0-6.0 millimeters.         -   Size.—The kernel is considered medium in size.         -   Form.—Considered generally ovoid. The fruit of the current             variety ripens before the kernel has had time to develop             completely, is still gelatinous, and principally exhibits             translucent cotyledons. Generally speaking, therefore, the             consistency and form of the kernel varies. Often the kernel             can shrivel, particularly at the base.         -   Kernel surface texture.—The kernel pellicle has a short             pubescence.         -   Color.—A dark tan (RHS Greyed-Orange Group 165 C). -   Use: The present variety ‘Burpeachforty’ is considered to be a peach     tree of the late season of maturity, and which produces fruit which     are considered to be firm, attractively colored, and which are     useful for both local and long distance shipping. -   Keeping quality: Appears excellent. The fruit of the present variety     has stored well for periods of up to 35 days after harvest at 1.0     degree Celsius. -   Shipping quality: Good. The fruit of the new peach tree variety     showed minimal bruising of the flesh or skin damage after being     subjected to normal harvesting and packing procedures. -   Resistance to insects and disease: No particular susceptibilities     were noted. The present variety has not been intentionally tested to     expose or detect any susceptibilities or resistances to any known     plant, fruit diseases, insect, frost, winter injury or other     environmental factors.

Although the new variety of peach tree possesses the described characteristics when grown under the ecological conditions prevailing near Fowler, Calif., in the central part of the San Joaquin Valley of California, it should be understood that variations of the usual magnitude, and characteristics incident to changes in growing conditions, fertilization, nutrition, pruning, pest control, frost, climatic variables and changes in horticultural management are to be expected. 

Having thus described and illustrated our new variety of peach tree, what we claim is new, and desire to secure by Plant Letters Patent is:
 1. A new distinct variety of peach tree, substantially as illustrated and described, and which is characterized principally as to novelty by producing an attractively colored yellow fleshed, clingstone peach which is mature for harvesting and shipment approximately June 12 to June 19 under the ecological conditions prevailing in the San Joaquin Valley of central California.
